which page calls my script

[Anon]

Is there a way to find out which page calls a php script?

like in:
<img src="counter.php">

I would like to know what the name of the page is with the html calling counter.php...
Or even better what's the name of the server hosting the html file?

$HTTP_REFERER sometimes works, but can be disabled by the client.
